Development and Validation of Biotechnology Knowledge Scale (BKS)
Keywords:Biotechnology, Biotechnology and Genetic Engineering, 8th grade students, Quasi-experimental study, STEM education, Survey
Biotechnology is at the heart of STEM education. Assessment of student understandings of biotechnology concepts is essential for designing learning and teaching. Thus, the aim of this study was to develop and validate the Biotechnology Knowledge Scale (BKS) for eighth graders in order to investigate their understandings biotechnology related concepts. The content validity was ensured by experts by comparison to the outcomes included in Turkish eighth grade curriculum. After the biotechnology subject was taught, the BKS was administered to a sample of 155 eighth grade students in three groups in Ankara in 2019-fall semester. The Cronbach alpha reliability coefficient of the BKS was calculated to be .770.
